Metamaterial-based active modulators can be created by placing graphene as a tuneable element shunting regions of high electric field confinement in metamaterials. However, in this common approach, the graphene is used as a variable resistor, and the modulation is achieved by resistive damping of the resonance. In combination with the finite conductivity of graphene due to its gapless nature, achieving 100% modulation depth using this approach remains challenging. Here, we embed nanoscale graphene capacitors within the gaps of the metamaterial resonators, and thus switch from a resistive damping to a capacitive tuning of the resonance. We further expand the optical modulation range by device excitation from its substrate side. As a result, we demonstrate terahertz modulators with over four orders of magnitude modulation depth (45.7 dB at 1.68 THz and 40.1 dB at 2.15 THz), and a reconfiguration speed of 30 MHz. These tuneable capacitance modulators are electrically controlled solid-state devices enabling unity modulation with graphene conductivities below 0.7 mS. The demonstrated approach can be applied to enhance modulation performance of any metamaterial-based modulator with a 2D electron gas. Our results open up new frontiers in the area of terahertz communications, real-time imaging, and wave-optical analogue computing.","PeriodicalId":18069,"journal":{"name":"Light-Science & Applications","volume":"223 1","pages":"256"},"PeriodicalIF":0.0,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144769674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, deep-tissue super-resolution imaging remains constrained by background interference, which leads to limited depth penetration and compromised imaging fidelity. To overcome these challenges, we propose a novel imaging system, confocal² spinning-disk image scanning microscopy (C2SD-ISM). It integrates a spinning-disk (SD) confocal microscope, which physically eliminates out-of-focus signals, forming the first confocal level. A digital micromirror device (DMD) is employed for sparse multifocal illumination, combined with a dynamic pinhole array pixel reassignment (DPA-PR) algorithm for ISM super-resolution reconstruction, forming the second confocal level. The dual confocal configuration enhances system resolution, while effectively mitigating scattering background interference. Compared to computational out-of-focus signal removal, SD preserves the original intensity distribution as the penetration depth increases, achieving an imaging depth of up to 180 μm. Additionally, the DPA-PR algorithm effectively corrects Stokes shifts, optical aberrations, and other non-ideal conditions, achieving a lateral resolution of 144 nm and an axial resolution of 351 nm, and a linear correlation of up to 92% between the original confocal and the reconstructed image, thereby enabling high-fidelity super-resolution imaging. Moreover, the system's programmable illumination via the DMD allows for seamless realization with structured illumination microscopy modality, offering excellent scalability and ease of use. Altogether, these capabilities make the C2SD-ISM system a versatile tool, advancing cellular imaging and tissue-scale exploration for modern bioimaging needs.","PeriodicalId":18069,"journal":{"name":"Light-Science & Applications","volume":"30 1","pages":"260"},"PeriodicalIF":0.0,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144769673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
